Patent ES-481446-A1 (ES)
Title: Hitch adapter
IPC: A01D67/00
Filed: 1979-06-11
Abstract: An agricultural tractor includes a rearwardly extending drawbar connected to a hitch member on the tongue of a trailing implement through a hitch adapter that includes a housing mounted on the rearward end of the drawbar and connected thereto by a vertical pin extending through a vertical bore in the housing and the drawbar, the rearward end of the adapter being pivotally connected to the implement tongue by a vertical pin, the axis of which is equidistant from the front and rear universal joints of a PTO hook-up assembly that connects the tractor power take-off to the implement driveshaft. The housing has a cavity with a larger cross section than the cross section of the drawbar and a plate-like clamping element is mounted in the housing cavity and includes upwardly and outwardly diverging inclined surfaces that are engageable with the lower lateral corner edges of the drawbar, the clamp member being vertically adjustable so that when the inclined surfaces engage the edges of the drawbar they clamp the drawbar against the top of the housing while resisting lateral shifting of the drawbar in the cavity, thereby providing a simple adjustment to accommodate the hitch adapter to various size drawbars.

Patent ES-8202207-A1 (ES)
Title: Forced commutated transistor inverter with power supply winding - has start=up supply taken from DC source which turns off automatically when operating
IPC: H02M7/538
Filed: 1981-03-18
Abstract: In the inverter two power transistors connect the prim. winding of a transformer alternately to opposite poles of a d.c. supply. A.C. voltages can be taken from the sec. windings. One sec. winding provides the power supply, typically 15 volts from a rectifier, for the regulator controlling the transistor switching. In order to start the inverter a temporary power supply is taken from the d.c. source. Typically this power supply is switched on by an NPN transistor which connects a simple stabilised voltage, typically 12 to 14 volts, to the regulator. When the inverter starts up the self-excited power supply takes over, on account of its higher voltage, and the start up supply turns off. The transistor can be protected against overload by a temp. sensitive switch between the base and zero voltage rail.

Patent ES-8301082-A1 (ES)
Title: Channel rejection filter
IPC: H03H11/34
Filed: 1981-12-30
Abstract: In a double-tuned circuit channel rejection filter for the greatest possible suppression of a television signal, preferably in UHF bands IV/V, and transmission with minimum attenuation in the remaining operating frequency range, the two parallel resonance circuits, constructed in chamber design and mutually shielded by a metallic partition are connected together via a connecting line and inductively coupled to the input and output terminal, respectively. To extend the possible uses for this channel rejection filter by improving the selectivity whilst at the same time increasing the depths of the rejection notch and return loss in a simple and inexpensive manner, the resonance circuits are constructed in such a manner that the connecting line compensates for the coupling inductances even at the highest UHF frequencies and produces adequate decoupling of the two resonance circuits. For this purpose, its dimensions are selected in such a manner that it exhibits a length of a quarter of the mean operating wavelength and the amount of its capacitive impedance approximately corresponds to that of the two coupling inductances in addition, the resonance lines of the two parallel resonance circuits in each case face the partition with their end section connected to earth and are arranged approximately perpendicular to the partition. A particularly advantageous possible use of this channel rejection filter in receiving systems consists in connecting it in parallel with a highly selective channel amplifier for amplifying the channel to be rejected in the channel rejection filter.

Patent ES-8402020-A1 (ES)
Title: Process for the lowering of the oxidation state of metal salts.
IPC: C22B3/00
Filed: 1982-06-01
Abstract: The oxidation state of metal salts is lowered by contacting a solution of the salt with polyacetylene in the presence of sufficient moisture to leave the polyacetylene substantially undoped. The metal salt must have a reductive capacity of at least +0.5. This process can be used to reduce metal salts to zero active valency metal. The moisture is effectively added by treating an aqueous solution of the salt, optionally with organic cosolvent. The zero valency metal can subsequently be recovered from the polyacetylene, for example by burning the polyacetylene off.

Patent ES-8403739-A1 (ES)
Title: Encapsulation by entrapment within polyhydroxy polymer borates.
IPC: A23L27/20
Filed: 1983-02-25
Abstract: Chemical biological agents to be encapsulated are dissolved or dispersed in an aqueous paste of a gel-forming polyhydroxy polymer. Subsequent addition of boric acid or a boric acid derivative at an alkaline pH converts the paste into a gel, thereby entrapping the agents in a protective matrix. Encapsulation of biologically active compositions provides a shield against hostile environments, improves safety in handling, and slows the release of such compounds to the surrounding medium. Highly volatile liquids are protected against losses by evaporation. Encapsulation also provides protection against decomposition from exposure to ultraviolet light.
